9v Claims.

This invention relates in general to a device adapted for use indairies, and in particular the invention is directed to, and it is oneof the objects to provide, a cow teat medicator.

In order to prevent spreading of certain diseases, such as mastitis,from one cow to another in milk-cow herds, it is desirable, and oftennecessary, to apply a disinfectant solution to the teats of the cowsafter milking, and the present invention is designed for this purpose;the device being hand supported and operated to readily and quicklyelect treatment tothe teats of a cow after milking.

A further object of this invention is to provide a device for thepurpose described, which cornpassage between the tank and the lower endof said cup, and a finger actuated pump associated with the tank `andteat cup operative to pump fluid from the tank upward into the teat cup;a check valve being interposed in said passage to prevent back-flow ofuid from the cup to the tank, and an overflow pipe leading from the cupadjacent its upper end downwardly to communication with said tank. y

A further object of the invention. is to produce a simple andinexpensive device and yet one which will be exceedingly effective forthe purpose for which it is designed.

These objects I accomplish by means ci such structure and relativearrangement of parts as will fully appear by a perusal of the followingspecication and claims.

The igure of the drawing is a side elevation of the device, partly insection.

Referring now more particularly to the characters of reference on thedrawing, the device comprises a relatively small upstanding tank Iformed at its upper end with a relatively large diameter neck 2 threadedfor the reception of a screw cap 3. A handle 4 is disposed outwardly ofand alongside the tank I, and includes an attachment finger 5 whichprojects inwardly to xed connection with the top of cap 3 to one side(Cl. 12S-248) be seen that not only is the cup t supported from the tankbut a passage P is formed therebetween.

A reciprocating sleeve pump, indicated at I0, is disposed in the tankand is mounted at its upper end in connection with the cap 3 and incommunication with the passage P. rIhis reciprocating sleeve pumpincludes an upwardly opening ball check lI at the lower end, and anotherupwardly opening ball check I2 in the nipple 8. f

Sliding movement of the reciprocating sleeve I3 of the pump isaccomplished by means of a pull rod i4 which extends from an ear I5 onsaid sleeve upward through an opening in the cap 3 to a ter'- minationin a head I 6 a short distance above said cap. IA finger actuated leverIl is secured at one end in loose play connection under the head I2 andis supported intermediate its ends for rocking movement by a fulcrumelement It; the otherl and outer end of the lever Il being formed asalinger piece I9 disposed above the handle 4. A compression spring 2Qsurrounds the rod It between the ear I5 and cap 3 whereby to normallymaintain the sleeve I3 in lowered position and with the ball check I Iadjacent the bottom of the tank.

A pair of oppositely disposed overiiow pipes 2I communicate with the cup6 adjacent 'but short of its upper end, and thence extend downwardly tothe cap and through which said pipes open at their lower ends. The capis formed at any con.- venient point with an air bleed-opening 22 fromwhich air can escape upon overflow of iiuid into pipes 2| and return ofsuch fluid to the tank.

In use, the tank I is filled with the fluid disinfectant and theoperator grasps the handle 4, and by means of which handle the devicecan be easily manipulated.

Holding the device in an upright position the operator actuates thelinger piece l up and down, which in turn actuates the pump I0, pumpingfluid from tank through passage P into the teat cup 6. The check valveI2 functions to prevent back flow of fluid from the cup into the pump.The operator continues such pumping action until the cup E is iillcd toa point adjacent the upper end 'of overflow pipes 2i. Thereafter thedevice is manipulated so that the cows teats are projected, one at atime, full length into the cup t, so that the fluid disinfectant, insaid cup successively treats the teats.

In practice I prefer to use an antiseptic solution which comprises abase of mineral oil to which the disinfectant and other ingredients areadded. The use of a mineral oil as the base is advantageous in that thesolution when used not only disinfects but conditions the cows teats,maintaining the same soft and pliable, which enhances milking, preventschailng, and heals small cuts and abrasions. For example, in the processof machine milking, the milk duct or teat opening of some cows oftenbecomes sore and inflamed, which in turn causes the cow to hold hermilk, making her a slow, hard cow to milk. I have found that after usingthe medicator with a solution as above, these ducts become soft andpliable, thus enabling the use of milking machines on cows thatotherwise would have to be milked by hand.

From the foregoing description it will be readily seen that I haveproduced such a de vice as substantially fulfills the objects of theinvention as set forth herein.

While this specification sets forth in detailthe present and preferredconstruction of the device, still in practice such deviations from suchdefined by the appended claims.

Having thus described my invention, what I claim as new and useful anddesire to secure by Letters Patent is:

l. A portable medicator for cow teats, comprising, in unitary relation,a tank adapted to receive a fluid, an upwardly opening teat cup 'mountedon and upstanding from the tank, means forming a passage from the tankto the cup, and means mounted in fixed connection with the tank to pumpfluid from said tank to the cup.

2. A portable medicator for cow teats, comprising, in unitary relation,a tank adapted to receive a fluid, an upwardly opening teat cup mountedin adjacent and fixed connection with the tank, means forming a passagefrom the tank to the cup, and means mounted in fixed connection with thetank to pump fluid from said tank to the cup; said last named meanscomprising a hand actuated pump, said pump including a check valveopening toward the cup and functioning to prevent back-flow of fluidfrom the cup to the tank.

3. A portable medicator as in claim 2 in which the teat cup is disposedabove the tank; and an overflow pipe connecting at one end in communilcation with the cup adjacent the upper end of the latter, and connectingat the other end in communication with the tank, the tank having arelatively small bleed hole in the top thereof. 4. A portable medicatorfor cow teats, comprising, in unitary relation, a tank adapted toreceive a fluid, an upwardly opening vertically elongated teat cupmounted in rigid connection with and upstanding from the top of thetank, means forming a passage from the tank to the cup at the bottom ofthe latter, a pump mounted in the tank in communication with saidpassage operative to pump fluid from the tank to the cup through saidpassage, a handle on said tank at one side thereof, and hand actuatedmeans to operate the pump.
